Boot camp assistant doesn't recognize the Windows 10 iso file.

Can you post the MD5sum? Here is an example (using a different ISO file).

You can do this in Terminal.

• Start Applications -> Utilities -> macOS Terminal
• Enter 'openssl md5'
• Use macOS Finder to find the ISO
• Drag the file to the Terminal window, and press enter.

openssl md5 Win10_1909_EnglishInternational_x64.iso 

MD5(Win10_1909_EnglishInternational_x64.iso)= d1f08aea37586702f6fbe2fe3ea8c3fd

Obtain official Microsoft images, untouched.

You could use the Microsoft tool for this, or a website like this: https://tb.rg-adguard.net/public.php

You can verify yourself that all images are downloaded straight from Microsoft.

I found the MD5sum, but I don't have a chance to get to the second line. After I put in the first line with the correct file name and return it, I get the response, "No such file or directory."

Did you drag & drop the Windows .iso file onto the Terminal window so it auto-fills the correct path to the .iso file?

Where did you obtain the W10 ISO from? What is the name and MD5sum of the ISO?

Did you check if your file is at least exactly 6221846528 bytes?

I have worked with the same on Big Sure 11.1 and it is recognised.

You are not in the correct folder containing the ISO. This is what you should get.

openssl md5 Win10_20H2_v2_English_x64.iso
MD5(Win10_20H2_v2_English_x64.iso)= 10d50d88fac6306a00ddb41e983a046b

Can you post a screen shot the of file in Downloads? If the file has a .downloads extension, then the download failed or is partially complete.

You should not need another license of Windows 10. The Audio issue is unrelated to your Office 365 issues.
